How do I solve this please help!

mr Goodwill [35]

Answer:

9 x + 8 y = 10 (I)

y = -4x + 7 (II)

One way is to rewrite the second as

4x + y = 7

Now multiply this equation by 8

32 x + 8 y = 56

9 x + 8 y = 10 and now subtract the equations

23 x = 46 this gives x as 2

From equation (II) y = -4 (2) + 7 = -1

So our values are (2, -1)

Check:

(I) 9 x + 8 y = 10 9 * 2 - 8 = 10

(II) 4 x + y = 7 or 4 * 2 - 1 = 7

Or you can substitute equation (II) directly into equation (I)

Please i need help on my math

Kamila [148]

Answer:

$V = \pi (2.5)^2h$

Step-by-step explanation:

The formula for the volume of a cylinder, is V = π r^2 h. It shows that the diameter is 5. But we need the radius. The radius is half of the diameter. So, 5/2. This gets you 2.5.

The equation is now:

V = π(2.5)^2h

This is the answer.

$V = \pi (2.5)^2h$
